Using the hashtag
PartyOnSawiris'Expense, supporters of al-Jazeera TV presenter Ahmed Mansour -
arrested and released in Germany - celebrated by mocking Egyptian businessman Naguib Sawiris on Twitter.
German authorities, reportedly acting on an Egyptian arrest warrant, detained the 52-year-old at a Berlin airport on Saturday. He was released on Monday after German officials said they had not been aware the arrest warrant was politically motivated.
Billionaire Sawiris had apparently been greatly pleased by the reporter's detention.
"Latest news.. Aljazeera announces that German authorities had arrested their presenter Ahmed Mansour at Berlin airport based on an Egyptian arrest warrant."Sawiris followed this tweet with another:
"Let's see what Qatar will do for you now??"
After Mansour's release, many Twitter users replied to Sawiris' post directly - many called him a traitor or gloated about his supposed humiliation.
